The bumpy rides in the city may soon come to an end with the introduction of a new road repair technology.

Rather than carrying out odd patchwork manually which takes hours, this new process, Nu-phalt In-situ Tarmac recycling system, just requires two persons and a van to repair a pothole in mere 22 minutes.

“The pothole is first manually made dust free and an infrared tarmac heater device is placed on it. After this the affected area is heated for about 200 degrees Celsius by a heater powered by gas and electrical feeder fitted in the van,” said Hemant Kumar, senior vice-president of Texmaco Limited, the company manufacturing the technology from UK based company Nu-phalt.

The working of the technology was demonstrated to officials of National Highway of India (NHAI) on Friday.

“The technology seems useful for pothole repairing and is environment friendly too,” said S.C. Jindal, chief general manager, corridor Management division, NHAI.

Earlier in the week the technology was also demonstrated to the Municipal Corporation of Delhi (MCD) which is contemplating using the technology on a pilot project basis.

After an interval of 20 minutes the heater is wheeled aside and the heated road material from the pothole is evenly spread in the cavity. Finally, a vibrator device is rolled over the affected area to level it with the road surface. Chances of pothole formation in the future are also reduced by use of this technology, the manufacturers claimed.

“The heat generated by the infrared heater creates a strong thermo bond between the repair area. Hence it will ensure that the patch work done will stay and potholes are not formed in the future,” said Vikas Jalan, managing director of Trans Metalite India limited that has imported the technology from UK.

In a manual pothole repairing process the traffic is disrupted, as it requires time for the repaired surface to cool off. In this system after the process is complete, traffic can immediately be allowed over the repaired surface.

Potholes in Delhi are formed quite frequently as the moment a road gets waterlogged, water seeps into the road surface and bitumen slips away from the aggregate, forming potholes.

The manufacturers claimed the technology is cost effective as only a small amount of new material is required and the entire existing tarmac is recycled.

It is environmentally friendly as not only does it reduce noise pollution but reduce carbon emissions by 92 per cent, they claimed.
